Safety instructions
•
Please read this instruction manual carefully and com-
pletely before using the headset.
•
Make this instruction manual easily accessible to all
users at all times.
•
Always include this instruction manual when passing
the headset on to third parties.
•
During flight operation, do not use the headset for
telephone calls.
•
With the NoiseGard™ active noise compensation
switched on, typical aircraft sounds (for example,
those from engines, propellers, warning alarms, etc.)
may sound different to you. Before operating any air-
craft, make sure that, with NoiseGard™ switched on,
you can hear and recognize these sounds. Set the
volume to safe levels that do not interfere with your
ability to hear informational sounds and warning
alarms.
•
The headset is capable of producing sound pres-
sure levels exceeding 85 dB(A). In many countries
85 dB(A) is the maximum legally permissible level for
continuous noise exposure during the working day.
Exposure to sounds of higher volume levels or for
longer durations can permanently damage your
hearing!
•
Never repair or attempt to repair a defective headset
yourself. Contact your Sennheiser agent or the
Sennheiser Service Department.
